Playing With Fire Part 2

Here is the scenario. There is a zombie apocalypse going on. It's sooooooo cold at night. All the electricity is gone and you have no heat. You'll surely die if you don't get warm soon. That's why I'm going to teach you guys how to make fire with items you will find in your house.
MATERIALS:
An orange
A knife
A dry rock
A stick


So, what you need to do is, take the knife and cut a small hole into the orange.  Make sure tha hole dosen't go all the way through the orange. Then, take off the part that you cut out. Take a small DRY rock and insert it inside the hollowed out orange. Take the DRY stick and rub it back and forth between your 2 palms.make sure the bottom of the stick is touching the rock. Then the orange will catch on fire!!!!! Voila!!! Instant survival!!!! Now, if only you don't die of hunger..............
